About this 1.25ct lab-grown emerald diamond

This 1.25ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG817653526 or 817653526. Listed at 5 retailers as of October 28, 2026, with prices from $302 to $625, a $323 spread on the same certified stone. Rare Carat lists it at $625. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
